Abstract (en)

[origin: EP1868009A1] The method involves calculating group-specific correction factors, amalgamating of the group-specific correction factors and derivating of network-specific correction parameters. In this partitioning, the reference stations (3) are represented by nodes in a connected, edge-weighted graph, in the generation of which, the distance connected by this edge is input into the weighting function of this edge. From the graph a minimum spanning tree is derived. An independent claim is also included for a computer program product as recording on a data medium or as electromagnetic carrier wave with code sequences.
